Hi, I have a Holley 4010 carburetor in my 1993 Prostar 205 with a 351 Indmar 285 hp with 740 hours. The 4010 is acting up and I need to either rebuild or replace it. I would like your advice:
Should I rebuild it?
Or should I replace it with a 4160?
If I replace it with a 4160, what other parts will I need in addition to the carb?
thanks, dale

You should probably post this in the Maintenance section or do a search this topic has been covered in other threads.

I read just long enough to see 4010. Replace. I'll go back and read the whole post now. :)

/edit. Yes, replace. I went through this same process and wasted $150 having it rebuilt before ultimately ditching it for the 4160. You'll need a new fuel line. Braided is probably the easiest way to go here as the solid ones aren't currently available for our fuel pumps.

You will be happy when proper idling is no longer a maybe.

I have a 4010 on my 93 with similar issues. Here is what fixed mine. Tighten the 4 bolts holding carb to manifold. Verify choke operation. Tighten all the Torxx screws on the carb. Any air leaks will affect idle. Verify motor temp doesnt exceed 160, if so get a lower temp t-stat. Doing all this will probably fix it. I would also add a new cap and rotor. I bought the rebuild kit for mine, and still don't need it.
